I tend to believe there is some problem there. At the minimum, behaviour is not consistent with what is explained in the manuals (under [G] axis_scale_options) -- at least last time I looked! Why, for example, do twoway scatter price mpg, plotregion(margin(20 20 20 20)) xscale(extend) yscale(extend) and twoway scatter price mpg, plotregion(margin(20 20 20 20)) xscale(fextend) yscale(fextend) produce the same graph? The manual says "If the plot region does have margins, extend would result in the y and x axes not meeting. With fextend they touch." Similarly, twoway scatter price mpg, plotregion(margin(20 20 20 20)) xscale(noextend) yscale(noextend) does not return anything I can understand. I had raised this issue with Tech-Support a while ago (this problem dates back to Stata 9 days).
